Sorry for not having the time to get back to you yesterday, but many thanks once again for the answer!
Same. I can't stand any traditional NTR with men, even if done in a femdom relationship, as I always feel that it detracts from the femdom experience and focuses on emasculation of MC in relationship to some other male character that does not even act submissively towards the mistress and is often dumb as a rock. NTR with a male character almost always works like a tool to shoehorn vanilla or sometimes even light maledom scenes into a femdom story, so I tend to avoid it like the plague!
As I said, I actually love the mistress cheating on MC with female characters, and I'm also perfectly fine with her having as many other male slaves as she wants besides the protagonist (I will even like scenes where many of them are forced to worship various parts of her body or punished/tortured at the same time), but her considering some vanilla or dominant male character more her 'equal' and 'superior' to MC actually makes me perceive that mistress as a less dominant character (who, you know, actually prefers to be dominated or 'roughed up' by a man and looks down on submissives for not being able to do the same thing, instead of craving their complete obedience and submission...) and therefore like her less, as it means that she at least has some switch/submissive tendencies as well.
I think traditional NTR is more of a humiliation fetish for people who like being humiliated and degraded
regardless of the sex of the person they are humiliated by, and while that's fine of course, it isn't and never was my cup of tea and, as I said, I believe it actually dillutes the experience of a femdom relationship, fictionally or otherwise.
You can of course do whatever you want with your own game - you already have plenty of great ideas that I'll look forward to, and the dominant path won't be one of them anyways, but I think a game always turn out best if the dev stays true to their vision, and while of course games can be improved by ideas, criticism or advice from fans, you should never let them dictate to you what to put in your game, as that can make you lose enthusiasm and creativity. If you want a sissy/femboy route in one of the dominant paths and have good ideas for it, don't let the fans tell you that you can't do it!
Well, while that's not quite my lezdom-femdom combined fetish (what I called Lesbian NTR), where MC is being cheated on by his mistress with another woman and he might end up serving the both of them in a more lowly position (say, MC licking the feet or worshiping the pussies of the two women and swallowing both of their juices as he kneels between their legs and they passionately kiss each other), I would also like the cuckqueen scenario if the Mistress does not enjoy MC dominantly fucking other women!
If she enjoys watching him have sex with and get dominated/humiliated by other women, I'd definitely also love it! If it's her simply enjoying to force MC to cheat on her in a vanilla way, just because she knows it hurts MC to do so because he only loves her or something of the sort, I probably wouldn't like it as much, as I won't find the sexual content of the act itself to be 'femdom' enough. (because essentially MC just gets to fuck pretty women - yes it might be a form of emotional torture and an expression of his mistress's control over his sex life, so I could like some elements of it depending on how it's written, just like I can mildly enjoy reverse rape femdom in some cases, but the erotic acts depicted would still be vanilla at the end of the day)
However, as I said, it's most important that you make the game that
you love, and I am already looking forward to a lot of things about Neuvau, (can't wait for more Leanne and Maureen,
and for Andrea's dominance to keep progressing!) so even if your cuckqueen fantasy is more like the latter scenario I described, not the one I said I would love, I'd have no problem with that being implemented into the game, and in fact I think there are plenty of people on this thread who would also find it hot!
Thanks again for your answer and I wish you a great evening!
